Abstract
The reconstruction problem is studied for a current pulse passing through a hollow cylindrical conductor (tube) such that the wall thickness is much greater than the thickness of the skin layer. The time dependence of the electric field intensity measured on the inner surface of the tube is used to reconstruct the current pulse. The proposed method allows us to study the evolution of the penetration of the magnetic field through the conductor thickness. The results for the test problems (both for the case of a constant temperature and for the case where the temperature varies over the tube thickness) are presented. Also, the current pulse is reconstructed via the electric field intensity measured at the inner surface of the tube within the experiment executed on the Angara-5-1 installation.
